The first domestic precision mask version of FMM process equipment has been shipped.

Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com January 7 news, Jingzhou equipment officially announced that the first domestic precision mask version (Fine Metal Mask, referred to as FMM) INVAR coil process equipment has passed the factory acceptance on January 6, and the shipping client will soon be put into production.

This is the first domestic INVAR coil process equipment independently developed and produced by Jingzhou equipment. The equipment integrates many units such as degreasing, pickling, thinning and cleaning, and can manage the thickness of the substrate to less than 20 μ m, so as to break the monopoly of foreign enterprises and solve the problem of "neck jam" of FMM process equipment in our country.

CTOnews.com query found that FMM is an important factor in the display industry, is the core component of OLED evaporation process, and its main role is to deposit RGB organic matter to form pixels in the production process. In view of the high requirements for the thermal expansion of FMM material in the evaporation process, the material is commonly used in Invar alloy, referred to as INVAR.

According to reports, the current FMM supply has been monopolized by overseas manufacturers, such as Japan and South Korea, which started earlier, and INVAR raw materials are limited by the trade agreement of origin, Chinese mainland FMM manufacturing enterprises are difficult to obtain less than 25 μ m thickness substrate, while high PPI OLED screen needs more exquisite holes, FMM manufacturers need to obtain thinner Invar raw materials, Invar raw materials have become a limiting factor for the development of China's OLED display industry.
